Oceanography-Chapter 6
If you were the captain of a sailing ship, which of the following latitudes would you want to avoid most
30°
The Trade Winds are one type of prevailing wind pattern. How many other types of prevailing winds are there among earth's global wind patterns?
2
Which of the following statements are true regarding the Anatomy of a hurricane?
Air moves from high to low pressure and curves to the right due to the Coriolis effect in the northern hemisphere, torrential rain and thunderstorms are coming within the spiral rain bands, warm moist air rises from the ocean surface creating a low pressure system
Why does wind between the equator and 30 degrees south come out of the southeast?
Cooled air moves north toward the equator and is deflected toward the west by the Coriolis effect.
What term is used to describe the effect on air movement produced by earths rotation?
Coriolis effect
What two factors explain why the prevailing westerlies blow toward the northeast in the northern hemisphere and the southwest in the Southern Hemisphere
Direction of circulation in the Ferrell cell and the coriolis effect
Why does air tend to rise in equatorial regions
Equatorial regions receive more direct sunlight than other areas.
What is the typical path for a North Atlantic hurricane to follow
It begins in the low latitudes of the Atlantic, is pushed westward by the Tradewinds, curves to the right due to the Coriolis effect, and then, once it is in the mid latitudes, is pushed to the east by the prevailing westerlies
How are rain patterns different near warm and cold fronts?
Rain near a cold front occurs over a smaller spatial area and is more intense than near a warm front.
Where does rain occur in a cold front?
Rain occurs along and behind a cold front.
Where does rain occur in a warm front?
Rain occurs along and in front of a warm front.
Even though it's on the same spinning planet the Coriolis effect influences moving objects and diverts them to the ___ of their intended direction in the northern hemisphere and to the ___ of their intended direction in the Southern Hemisphere
Right left
Areas of low pressure tend to have __ air and __ weather
Rising stormy
Why does rain occur near a cold front?
Rising warm air cools, resulting in cloud formation and rain.
Why does rain occur near a warm front?
Rising warm air cools, resulting in cloud formation and rain.
What conditions are required for a hurricane to form
The coriolis effect and warm ocean temps
Why don't tropical storms that form on the equator develop into hurricanes?
The coriolis effect is absent
What did the NASA satellite measure as it made passes above hurricane Arthur in 2014
The extent and intensity of the rain bands
If earth rotated in the opposite direction how would global atmospheric circulation be affected
The global wind belts would blow in the opposite east west direction
As shown in the video, what causes the item to deflate?
The higher pressure inside the item forces the air out into the lower pressure of the room.
What determines whether a front is called a cold or warm front?
The type of front is determined by which air mass is moving
What is the air that sinks at latitudes of 30 degrees north and south like?
This air is cool and dry.
In which direction would winds move at the poles if earth rotated in the opposite Direction
Wind from the North Pole would move to the southeast and the wind from the South Pole would move to the northeast
What common household item is used in this video to demonstrate differences in atmospheric pressure
balloon
As discussed in the video, air always moves from _____ atmospheric pressure regions to _____ atmospheric pressure regions.
high to low
Which way would wind travel in the region between 30 and 60 degrees latitude if earth stopped rotating
south in the Southern Hemisphere and north in the Northern Hemispheres
What is a front?
the boundary between two air masses of different temperatures
What older household item is used in this video to demonstrate the Coriolis effect?
turntable, record player
The coriolis effect is __ at the equator and is __ at the poles
zero; strongest
